A DSP/BIOS AIC23 Codec Device Driver for the TMS320DM642 EVM

This document describes the usage and design of a device driver for the AIC23 audio codec on the TMS320DM642 EVM. This device driver is written in conformance to the DSP/BIOS™ IOM device driver model and uses the generic TMS320C6x1x EDMA McASP driver to transfer samples to and from the serial port. For details on this generic driver, see the application note A DSP/BIOS EDMA McASP Device Driver for TSM320C6x1x DSPs (SPRA870).
